Steam then mash or puree cauliflower. Add butter, salt, pepper, milk then sprinkle cheese on top. It's SO good b/c it's so much like mashed potatoes! Around 108 calories for 1 cup for the pureed cauliflower. Compare that to 237 calories for 1 cup of mashed potatoes. But who am I fooling? I don't count calories. I eat it b/c it's good!
